-- OBJECTIVE:
--      Check that a type derived in a client of a public child inherits 
--      primitive operations from parent.  
--
-- TEST DESCRIPTION:
--      Declare a root record type with discriminant in a package 
--      specification. Declare a primitive subprogram for the type 
--      (foundation code).
--
--      Add a public child to the above package.  Derive a new type 
--      with constraint to the discriminant record type from the parent 
--      package.  Declare a new primitive subprogram to write to the child 
--      derived type.
--
--      In the main program, "with" the child.  Derive a new type using the 
--      record type from the child package.  Access the inherited operations 
--      from both parent and child packages.
--
-- TEST FILES:
--      This test depends on the following foundation code:
